TECHNICAL FIELD

The present invention relates to a control device for monitoring and controlling home appliances.

BACKGROUND ART

Recently, along with the rapid development of wired/wireless data communication technology and the broad distribution of communication networks, high-speed communication services such as the Internet have been widely popularized. In particular, as high-speed Internet service has been provided in households, conventional PC-based network technology has developed into home network technology for remotely controlling digital home appliances.

A home network system is a system for connecting digital home appliances, sensors, light fixtures, heating and cooling devices, gas devices, and so on over a wired or wireless local area network to control appliances desired by a user anywhere at any time.

Such a home network system typically includes a home server (or a home monitoring gateway) that functions as a master, a plurality of home network devices (hereinafter referred to as control target devices) that are monitored and controlled by the home server, and a controller that locally or remotely monitors and controls a plurality of control target devices through a connection with only the home server.

In this case, the home server is generally implemented on a residential gateway (RG) or a wall pad, and a controller is generally implemented in a wall pad, a TV, a cell phone, a computer, etc. The home server and the controller may be integrated and implemented as one device. For example, a TV may serve as the control device in addition to the home server.

In the home network system, the home server may automatically recognize control target devices, for example, a TV, a refrigerator, a lamp, a microwave, a sensor, a boiler, and a washing machine, which are connected to a home network through various physical media (e.g., a power line, a serial communication such as RS-232, Ethernet, etc.), and may display the recognized home network devices on a screen to control devices desired to be controlled by a user.

The controller monitors and controls a plurality of control target devices through communication with the home server.

In the home network system, the home server transmits data to or receives data from an external network, which is mainly implemented as an Internet network.

The user uses a control device such as a PC, a notebook, a smartphone, a tablet PC, a TV, a wearable device, and various remote controllers to access the home server located inside or outside the home and then access a plurality of home appliances connected to the home network inside the home.

In addition, when a plurality of electric devices are registered with an external server, the user accesses the plurality of electric devices registered with the external server via the external server, irrespective of the home server.

When the user uses the control device to monitor and control the control target devices inside the home, the use should select one of the control target devices, access the selected control target device over a network, perform authentication, and then monitor or control the control target device. Thus, it is difficult for the user to use the control device.

For example, home appliances such as an air conditioner or air cleaner for conditioning an air and a humidifier for adjusting humidity are usually controlled together. In this case, the user should inconveniently and inefficiently issue an operation control command to each electric device.

The term “direct switching” includes switching the screen through a single touch rather than the sliding touch.

That is, the screen switching unit 315 includes page buttons equal in number to the plurality of screens. The arrangement of the plurality of page buttons corresponds to that of the plurality of screens. A page button corresponding to the position of the currently displayed screen is displayed differently from the remaining page buttons. Thus, the user may recognize the position of the currently displayed screen.

In addition, arrangement information of the plurality of screens may be preset, and the arrangement of the screens may be changed by the user.

For example, the user interface unit according to the embodiment includes a total of three screens, that is, the dashboard screen, the first plug-in screen, and the second plug-in screen. For the arrangement of the three screens, the first plug-in screen is disposed at the left side of the dashboard screen, and the second plug-in screen is disposed at the right side of the dashboard screen.

In addition, the overview unit 311 further includes a movement button A2 for moving a screen on which the icons of the pre-registered electric devices are arranged.

That is, the movement button A2 is a button for moving the currently displayed icon to change a display position of the icon in order to display icons of the remaining electric devices that are hidden and not displayed on one screen in the overview unit.

In this case, the movement button A2 is in a hidden state when the number of icons of the pre-registered electric devices is less than a predetermined number of icons that can be displayed on one screen. The movement button A2 is in a displayed state when the number of icons of the pre-registered electric devices is greater than the predetermined number of icons that can be displayed on one screen.

The movement button A2 includes a first direction button < that instructs to move from a currently displayed screen to a screen extending in a first direction, and a second direction button > that instructs to move from the current displayed screen to a screen extending in a second direction. Here, the second direction is a direction opposite to the first direction.

When the first direction button < is selected, the overview unit 311 shifts icons of a predetermined number of electric devices in the current screen by one column in the second direction to rearrange the icons. When the second direction button > is selected, the overview unit 311 shifts icons of a predetermined number of electric devices in the current screen by one column in the first direction to rearrange the icons.

In this case, when the first direction button < is selected, the overview unit 311 rearranges an icon of a new electric device at the leftmost column of the screen and removes an icon of an electric device that has been positioned at the rightmost column. When the second direction button > is selected, the overview unit 311 rearranges an icon of a new electric device at the rightmost column and removes an icon of an electric device that has been positioned at the leftmost column.

When the first direction button < is touched while the icons of the air conditioner2, the robot cleaner2, and the television are displayed, the overview unit 311 moves the currently displayed screen to the left screen and displays the icons of the cleaner, the light fixture, the washing machine, and the air conditioner positioned on the left screen again.

Although the movement button of the overview unit 311 is touched, the control unit 320 controls the user interface unit 310 such that screens of the widget units 312, 313, and 314 are maintained in the current state.

In addition, the overview unit 311 further includes a speech bubble A3 that informs about an on/off state or a progressive state, which indicates a current operation state, of a pre-registered electric device. The speech bubble A3 is positioned in the vicinity of the icon A1 such that the speech bubble A3 is easily recognized by the user.

The speech bubble A3 changes a notification indicating an operation state of an electric device on the basis of a command of the control unit 320.

That is, when any one of the icons displayed in the overview unit 311 is touched, the control unit 320 changes the operation state of the electric device corresponding to the touched icon and controls the user interface unit 310 such that the changed operation state is displayed in a speech bubble.

For example, when the icon of the air conditioner is touched while the air conditioner is in an on state, the control unit 320 controls the air conditioner to be powered off and controls the user interface unit 310 such that the off state of the air conditioner is displayed in the speech bubble. When the icon of the air conditioner is touched while the air conditioner is in an off state, the control unit 320 controls the air conditioner to be powered on and controls the user interface unit 310 such that the on state of the air conditioner is displayed in the speech bubble.

As shown in FIG. 5, on a condition that the icons of the robot cleaner, the light fixture, the washing machine, and the air conditioner are displayed, the overview unit 311 utilizes the speech bubble to inform that the operation of the air conditioner is powered off when the icon of the air conditioner that is powered on is touched, and utilizes the speech bubble to inform that the operation of the robot cleaner is cleaning when the icon of the robot cleaner that is power off is touched.

In addition, when the icon of a washing machine is touched while the washing machine is in an on state, the control unit 320 checks a work-in-progress state of the washing machine and controls the user interface unit 310 such that the checked work-in-progress state of the washing machine is displayed in the speech bubble.

As shown in FIG. 6, when an icon of the washing machine in an on state is touched while the icons of the robot cleaner, the light fixture, the washing machine, and the air conditioner are displayed, the overview unit 311 utilizes the speech bubble to inform that a progress state of the washing machine is “one hour and ten minutes have passed.”

In addition, the control unit 320 may check at least one of an update state, an error state, and a reservation state of the pre-registered electric device, and may control the user interface unit such that the checked state information is displayed in the speech bubble.

That is, the speech bubble A3 informs about any one of the update information, the error information, and the reservation information of the electric device.

In addition, when an operation state of at least one electric device is changed in response to a touch input to a master key 312 of the widget unit and a chatting instruction input of a chatting unit 313, the control unit 320 controls the user interface unit 310 such that the changed operation state is displayed in a speech bubble.

In addition, the user interface unit can display the icon list and the device names of the plurality of electric devices displayed on the conversation display window 610 and receive a device name of an electric device through the conversation input window 620.

That is, the control unit of the control device checks whether an instruction, that is, a message displayed on the conversation input window 620 is a duplicated instruction corresponding to the plurality of electric devices. When the instruction is determined to be duplicated, the control unit displays a list of icons of the plurality of electric devices associated with the duplicated instruction on the conversation display window 610 of the chatting screen of the user interface unit.

When at least one icon is selected from the list of icons of the plurality of electric devices displayed on the conversation display window 610 of the user interface unit, the control unit of the control device checks an electric device corresponding to the selected at least one icon and displays the device name of the checked electric device on the conversation input window 620.

Furthermore, the control device stores information about electric devices for each duplicated instruction and stores an operation command for each electric device.

For example, when a “Turn off” instruction is input as the duplicated instruction while an icon for all devices is displayed in the icon selection window 630 of the chatting screen, the user interface unit checks electric devices to which the “Turn off” instruction may be applied, that is, electric devices being turned on and displays a list of icons or device names of the checked electric devices.

The user interface unit receives a touch on an icon of at least one electric device from the list of icons of the electric devices or receives the device name through the conversation input window and transmits an “Turn off” operation command to the received electric device.

As shown in FIG. 27, when a name of a specific electric device (or a specific input for identifying an electric device) is input through the text window 650, the conversation state is changed to the corresponding electric device irrespective of the current conversation partner.

For example, the user interface unit checks whether the message displayed on the conversation input window 620 is the device name. When the checked message is determined to be the device name, the user interface unit checks an electric device having the determined device name and displays an icon of the checked electric device on the icon selection window 630.

When a message is input through the text window 650, the user interface unit displays the input message on the conversation input window 620. When a send button 640 is touched after the message displayed on the conversation input window 620 is input, the user interface unit displays the input message on the conversation display window 610, checks the input instruction on the conversation input window 620, and displays the checked “Recharging” instruction on the conversation display window 610.

For example, when “recharge robot cleaner” is input, the conversation partner is changed to the robot cleaner although previous conversation partners are all devices (a house shaped icon), a control command to recharge is transmitted to the robot cleaner. In addition, the conversation partner icon is changed to the robot cleaner.

The control unit of the control device transmits an operation command corresponding to the checked “Recharging” instruction to the robot cleaner, receives information about a recharging operation from the robot cleaner, and allows the received information to be displayed on the conversation display window 610 of the user interface unit.

An example of inputting an instruction of the chatting screen of the user interface unit will be described in detail with reference to FIGS. 28 to 33.

As shown in portion (a) of FIG. 28, the user interface unit directly receives natural language the user uses through the conversation input window of the chatting screen. As shown in portion (b), the user interface unit selects an instruction preset for each operation command and receives the selection through the conversation input window of the chatting screen. As shown in portion (c), the user interface unit displays an icon target window for each electric device and a shortcut word button window 632 for which an instruction for each electric device is set on the chatting screen and receives a touch on an icon and a button or receives an input through voice.

When the input is received through voice, the control device may display the recognized voice on the conversation window. In addition, when the input is received through voice, the control device may display a group of instruction candidates for the recognized voice and the group may be displayed such that the user selects an appropriate instruction from the group.

As shown in FIG. 29, when the message displayed on the conversation input window 620 is the device name, the user interface unit displays an icon of an electric device having the device name on the icon selection window 630. When the conversation input window 620 is touched in the manner of a tap or a long-tap, the user interface unit displays the preset instruction list. In this case, the instructions are set as a list for each electric device.

When any one instruction is touched from the preset instruction list, the user interface unit displays the touched instruction on the conversation input window 620. When the send button is touched by a user, the user interface unit displays a devices name and an instruction of an electric device that are input to the conversation display window 610.

The control unit of the control device checks whether the message displayed on the conversation input window 620 is the device name. When it is determined that the checked message is the device name, the control unit checks the electric device having the determined device name and displays an icon of the checked electric device in the icon selection window 630.

For example, when “Robot Cleaner” is input to the conversation input window 620, the user interface unit displays an icon of the robot cleaner on the icon selection window 630. When the conversation input window 620 is touched as a tap or long-tap, the user interface unit displays a preset instruction list for controlling the robot cleaner.

When Turn-off is touched from the preset instruction list, the user interface unit displays the touched instruction on the conversation input window 620. When the send button is touched, the user interface unit displays a conversation selected by the user on the conversation display window 610.

As shown in FIG. 30, when the message displayed on the conversation input window 620 is the device name, the user interface unit displays an icon of an electric device having the device name on the icon selection window 630 and displays a list of instructions that begin with at least one character input through the text window 650. That is, when the at least one character is input, the user interface unit displays an instruction based on an automatic completion function.

When any one instruction is selected from the instruction list, the user interface unit displays the selected instruction on the conversation input window 620. When the send button is touched, the user interface unit displays the device names and instructions on the conversation display window.

Furthermore, the control device stores an instruction and order information of words composing of the instruction.

For example, when “Robot Cleaner” is input through the text window 650, the user interface unit displays a robot cleaner on the conversation input window 620 and also displays an icon of the robot cleaner on the icon selection window 630. When “s” is input through the text window 650, the user interface unit displays a list of instructions that begin with “s.”

When “start” is selected from among the instructions that begin with “s,” the user interface unit displays “start” on the conversation input window 620. When the send button is touched, the user interface unit displays the device name (Robot Cleaner) and the instruction (start) on the conversation display window 610.

As shown in FIG. 31, when the message displayed on the conversation input window 620 is the device name, the user interface unit displays an icon of an electric device having the device name on the icon selection window 630 and displays an instruction input through the text window 650 on the conversation input window. When the send button is touched, the user interface unit displays the device name and the instruction on the conversation display window.

When the input instruction is an unrecognized instruction, the user interface unit displays an instruction that is most similar to the input instruction as a selectable button. When the displayed button is selected, the selected instruction is displayed again along with the device name.

In this case, the control unit of the control device determines a similarity of words between the input instruction and instructions of the electric device having the input device name, determines an instruction having a similarity equal to or greater than a certain value, and selects the determined instruction as a similar instruction.

For example, when “Robot Cleaner” is input through the text window 650, the user interface unit displays a robot cleaner on the conversation input window 620 and also displays an icon of the robot cleaner on the icon selection window 630. When “star” is input through the text window 650, the user interface unit displays “start,” which is a command that is the most similar to “star.”

That is, the control unit of the control device compares words composing of an instruction for controlling the robot cleaner with ‘star’ and determines “start,” which is a command that is the most similar to “star,” as the similar instruction.

As shown in FIG. 32, when the message displayed on the conversation input window 620 is the device name, the user interface unit displays an icon of an electric device having the device name on the icon selection window 630 and displays, as a recommended instruction list, an instruction based on the operation state of the electric device having the device name. When any one instruction is selected from the recommended instruction list, and then the send button is touched, the user interface unit displays the device name and the instruction on the conversation display window 610.

In this case, the control unit of the control device checks the operation state of the electric device having the input device name, checks an executable operation command on the basis of the checked operation state, and checks an instruction corresponding to the checked operation command.

For example, when “Robot Cleaner” is input through the text window 650, the user interface unit displays a robot cleaner on the conversation input window 620 and also displays an icon of the robot cleaner on the icon selection window 630. The user interface unit displays a recommended instruction list on the basis of the operation state of the robot cleaner.

When an instruction “stop” is selected from the recommended instruction list, the user interface unit displays “stop” on the conversation input window. When the send button is touched, the user interface unit displays the device names and instructions on the conversation display window 610.

In this case, when the robot cleaner is determined to be in a charging operation, the control unit of the control device checks an executable operation, checks an instruction for controlling the checked operation, and displays a start instruction instructing to start cleaning and a stop instruction instructing to stop recharging in the recommended instruction list.

As another example, when the air conditioner is being stopped, the control unit may display an operation start command as the recommended instruction. When the air conditioner is in operation, the control unit may display an operation stop instruction, a target temperature up/down instruction, and an operation mode change instruction.

As shown in FIG. 33, when the message displayed on the conversation input window 620 is the device name, the user interface unit displays an icon of an electric device having the device name on the icon selection window 630. When a preset shortcut letter is input through the text window 650, the user interface unit displays the shortcut letter on the conversation input window.

When the send button is touched, the user interface unit displays an instruction corresponding to the device name and the shortcut letter on the conversation display window 610.

In this case, the control device stores an instruction for each shortcut letter. In this case, the instruction for each shortcut letter may be set differently depending on the electric device.

That is, the control unit of the control device checks an instruction corresponding to the input shortcut letter and controls a display of the checked instruction.

For example, when “Robot Cleaner” is input through the text window 650, the user interface unit displays a robot cleaner on the conversation input window 620 and also displays an icon of the robot cleaner on the icon selection window 630. When “c” is input through the text window 650 and then the send button is touched, the user interface unit displays the instruction “clean” having the shortcut letter of “c” on the conversation display window 610 in addition to the device name (Robot Cleaner).

In this case, it is possible to easily chat with an electric device by inputting an instruction using the shortcut letter upon the chatting.
